I'm secure enough in my masculinity to admit that I played with some nail polish I picked up for cheap at the flea market. Turns out kokanee really like bubblegum pink on just about any lure.
You can find bags of premade lure blanks in wood and plastic (flatfish, poppers, crank bodies etc.) online.
There were some really cool older posts here where CFF members used fine fishnet mesh and air brush to paint scales, etc. Don't know if those old pics will show up anymore on a search though. . .
